'COOKING RANGE.

Application led June 3,r 1922. i Serial No. 565,681.

To all whom t may concern: n

Be it known that l, ALBERT, A. BRUDER, a citizen of the United States ofAmerica, residing at Holly, in the county of Oakland and State ofMichigan, have invented certain new and useful Improvements in CookingRanges, of which the following isl a specification, reference being hadtherein yto the accompanying drawings. Y

This invention relates to a cooking range of that class in which hotfuel, as coal is utilized for heating ovens and a cooking top, althoughthe construction of my range permits of various kinds of fuel burnersbeing installed.

A cooking range in accordance with my invention may be characterized inthe fol lowing particulars,

First, there is a central magazine combustion chamber with a warmingoven above the same and baking ovens at the sides of the combustionchamber with said baking ovens providing cooking tops separated by theupper portion of the combustion cham# ber and permitting of each cooking.top being conveniently used. design of the cooking range is practicallytwo stoves in one or a common combustion chamber serving two cookingunits;

Second, the arrangement of floues about-y the baking ovens permits ofheated air being withdrawn from the hottest part of the combustionchamber and circulated about the baking ovens to thoroughly heatthewalls thereof, the circulation being somewhat retarded before finalexhaust so as to utilize any latent heat during the yoperation of thecooking range.

Third, the air supply necessary for a thorough combustion of coal in themagazine combustion chamber is taken care of by an air inlet pipedisposed to produce a siphonic action at the upper portion of thecombustion chamber so as to withdraw any gases, smoke, or unconsumedgaseous prod-y ucts of combustion and deliver the same beneath the liregrate of the combustion chamber. In the full operation of the cookingrange the draft through the fire grate or the unconsumed products ofcombustion delivered thereto produces an extremely live fire and hotfire bed, with the result of .a minimum waste of fuel and a minimum heatduring the operation of the cooking range.

Fourth, there is an arrangement of dainpers which will permity of smoke,dust ln other words, the' the line IV-V of Fig. l;

laden `air and gases exhausting to the atm/os# phere during the firingof the 4cooking range or ythe removal of ashes therefrom, otherwisesuch'exhaust is defiected, by reason of the ysiphonic actiony'previously mentioned and such exhaust made lindirect to the atmospherewith the exhaust gases subjected 'to the action of the lire within thecombustion chamber in `order that any unconsumed products of combustionmay be burned.

Fifth, the upper portion of the cooking range includes a water tank yorreceptacley surrounding a portion of the combustion chamber whereby theheated walls of said chamber may heat water in the tank or receptacle.In o ther` words the tank or jacket about the combustion chamber isadapted to provide a source of warm water similar to kthe ordinary andwell known type of hot water boiler or water back to the cooking stove.f

The above are a few of the features of.

myy cooking range and others'may appear as the construction is describedby aid of the drawings, wherem- Figure l isv a vertical'longitudinalsectional view of the cooking range; f

Fig. 2 is a horizontal sectional `View of the samek taken approximatelyon the line II-II of Fig. l; f

Fig. 3 is a rear elevation section;y

Fig. i is a detail sectional view of one of the dampers of the cookingrange, taken on Fig. l5 is a vertical cross sectional view taken on theline V-k-V of Fig.l 1;

Fig. 6 is a. similar view taken onthe line VI-VI of Fig. `l,`and f fFig.-7y 's a front elevation, on a small scale, of the cooking range.r

In the drawings, the reference numeral l denotes a base or range bottomthat may be supported directly on a floor or by suit able legs 2. On thebase is an oblong boxlike structure comprising a front wall 3, end walls4 and a rear wall. i

Onthe upper edges of the walls 3, A@fand 5 areend cooking tops 6provided with the usual openings and lids 8. Between the end cookingtops 6 and extending upwardlyl yof the cooking; range, partly brokenaway and partly in combustion ychamber the full depth of the range. y

The upper portion ofl the walls 16 are disposed parallel and in spacedrelation to theside walls to form water jacketsor receptacles 17communicating with 'each other -by a conduit 18 suitably mounted on theyrear wall 11, said wall having openings at the jacket 17 in order thatwater may circulate through said'jackets, one ofwhich y has a waterinlet pipe 19 andthe other a water outlet pipe 20. The wallsl of thejackets 17 and the conduit 18 will be heated during the operation of therange and there will be at all times an available source o warm water.

The lower portions of the walls 16 have confronting ledges 21`supporting a conventional form of grate 22 which has been illustratedas the rocker type. The grate divides the combustion chamber to the eX-tent-.ot providing an ash pit 23 and access ishad* thereto b-y a door 24carried by the front wall 3.

The ash pit or lower portion of the combustion chamber divides the rangestructure and in the ends of said structure, below the end cooking tops6, are rectangular baking ovens 25 the full depth of the range; accessbeing had to the front ends of said ovens by doors 26 carried by thewall 3. The oven walls are in spaced relation to the walls of the rangestructure so as to provide top iiues 27 under the cooking tops 6;' endiiues 28 ;k bottom tlues 29, and battle fines 30, said batie lues beingbetween the baking ovens and the ash pit 23 of the combustion chamber.`The innermost walls of the baking ovens 25 are carried downwardly tojoin the base'or range bottom 1 for approximately half the depth oitlthe range, as best shownin Fig. 6, thus leaving openings 3i at the frontside of the range establishing communication between the flues 29 and30. In the baffleflues 30 are bailles or deflectors 32 and 33, theformer extending upwardly Jfrom the base or range bottom 1 in the middleportion of the baflie flue7 and the latter' extending downwardly yfromthe top ot the battle flue to a vpoint between the baiiie 32 and therear wall 5, said wall having an opening 34 at the rear end of eachbaliie flue. lt is now apparent that any warm air followingthe directionof the arrows showny in. Fig-1, aboutthe baking ovens 25,

must pass through the openings 31 upwardly into the battle liues 30,over the bailles 32, under the batlies 33, and outwardly through theopenings 34. The battles within the baiiie Hue tend to retard theprogress or exhaust of heated air and thus insure a uniform temperatureabout the oven walls.

The baille iiues 30 have inclined top walls 35 and the water jackets 17have inclined bottom walls 37, said walls cooperating with the front andrear walls of the range structure in providing passages 36 establishingcommunication between the top flues 27 and the combustion chamberdirect-ly above the grate 22.

Mounted against the rear walls 5 and 11 is a casing 38 containinglongitudinally*` disposed parallel partitions 39 which meet below anexhaust connection 40 o1 the casing, said partitions providing exhaustlues 41 and a down iiue 42. rlhe exhaust flues 41 communicate with theopenings 34 of the baffle lues 30 and with openings 43 in the wall 11below the horizontal partition 13, said openings, at times, establishingcommunication between the exhaust flues 41 and the upper portion of thecombustionchamber.

rlfhe down iiue 42 has its lower end communicatingy with an opening 44in the rear wall 5, said opening communicating with the ash pit 23. rlheupper end of the down flue communicates with the combustionchamberthrough ali-opening 45 in the wall 5 and extending through theopening 45 is a cold air inlet pipe 46y having its front end supportedby the wall 9 and communica-ting with the atmosphere by means of adamper or shutter 47. The rear end of the cold air inlet pipe 46-extendsdownwardly in the down flue 42 and air entering the down iiue from thepipe' 46 is adapted to produce a siphonic action at the openingv 45 anddraw oit any smoke, gases or unconsumed products of combustion from thecombustion chamber. Such smoke and gases enters the ash pit 23, passesupwardly through the grate 22 and are burned by the bed of lire on thegrate. Such gases as are not burned become heated and passl around thebaking ovens 25 to eventually entery the exhaust flues 41 and the outletconnection 40 of the casing 38.

ln the cold airinlet pipe 46y or adjacent the opening 45, is a damper 43on i damper rod 49 suitably mounted in the chamber wall 16 and one ofthe walls 10 so e The 'Vall 9 has a suitable door 51 below the oven doorl5 and the door 5l permits of the upper portion or magazine off thecombustion chamber being loaded with yfuel, for instance to the heightindicated by the broken'line in Fig. 1. The tire ybed will be maintainedabove the grate 22 andy partly in the passages 36, as indicated bybroken lines in said passages and consequently an intense heat will bein the top lues below the cooking tops 6. It will be noted that thebottoni walls 37 of the water jackets 17 are subjected to such heat.

When fuel is to be placed in the combustion chamber the dampers 50 areopened and consequently the damper 48 isv closed. Since the door 5l willbe opened a draft will be produced rearwardly in the combus tion chamberto carry smoke and gases into the exhaust lues 4l, instead of throughthe opening 45 into the down flue, there being no siphonicaction'because the damper 48 is closed. This is only during the tiringof a stove and after the door 5l is closed the damper 48 vmay be opened,so that unburned gases or fumes will bev directed' downwardly into theash pit to pass through the bed of fire and be substantially consumed.

For fear that soot and other matter may accumulate in the lower ends ofthe iiues 4l and 42 the casing 38 is provided with doors 52 that may beopened and the lues cleaned out.

It is thought that the operation and utility of the cooking range willbe apparent without further description, and while in the drawings thereis illustrated a preferred embodiment of my invention, it is to beunderstood that the structural elements are susceptible to suchvariations and modifications as :tall within the scope of the appendedclaims.
